Subuniformity of harmonic mean p$$ p $$‐values

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We obtain several inequalities on the generalized means of dependent p$$ p $$‐values. In particular, the weighted harmonic mean of p$$ p $$‐values is strictly subuniform under several dependence assumptions of p$$ p $$‐values, including independence, negative upper orthant dependence, the class of extremal mixture copulas, and some Clayton ...

An observation‐driven state‐space model for claims size modelling

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract State‐space models are popular in econometrics. Recently, these models have gained some popularity in the actuarial literature. The best known state‐space models are of the Kalman‐filter type. These are called parameter‐driven because the observations do not impact the state‐space dynamics.

Optimal dividends for a NatCat insurer in the presence of a climate tipping point

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We study optimal dividend strategies for an insurance company facing natural catastrophe claims, anticipating the arrival of a climate tipping point after which the claim intensity and/or the claim size distribution of the underlying risks deteriorates irreversibly.

Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Bromazolam Tablet Quantification and Analysis of Post‐Mortem Cases From the National Programme on Substance Use Mortality (NPSUM)

open access: yesDrug Testing and Analysis, EarlyView.
Tablets submitted to drug checking services that were found to contain bromazolam. Over half of these counterfeit tablets mimicked the appearance of licensed formulations (e.g., alprazolam Xanax bars and diazepam Roche 10 mg pills). Bromazolam is now the most commonly detected street benzodiazepine in drug poisoning deaths in the United Kingdom ...

The Impact of Renewable and Non‐Renewable Energy on Economic Growth: Evidence From Sub‐Saharan African Countries Using Multivariate Panel Vector Autoregressive Modeling

open access: yesEnergy Science &Engineering, EarlyView.
This study analyzes energy consumption and economic growth across 39 Sub‐Saharan African countries using a PVAR model. Findings reveal that non‐renewable energy and labor force growth stimulate economic growth, while renewable energy does not stimulate economic growth in the short run.

Disease Site‐Specific Outcomes in p16‐Positive Non‐Oropharyngeal Mucosal Head and Neck Cancer

open access: yesHead &Neck, EarlyView.
ABSTRACT Objectives To report disease‐free survival (DFS) in p16‐positive non‐oropharyngeal head‐and‐neck squamous‐cell carcinoma (HNSCC). Methods Curatively‐treated non‐oropharyngeal HNSCC (2009–2021) were reviewed. DFS was compared among p16‐positive, p16‐negative, and p16‐untested cases for the overall cohort and by disease site.
